Specification of Letters Patent.

Patented April 21, 1908.

Application filed July 9, 1907. Serial No. 382,893.

To all 'whom it may concern: v

Beit known that I, ELI S. GLovER, a citizen of the United States, residing at Chicago, in the' county of Cook and State of Illinois,-

have invented certain new and useful Im` rovements in Iercolators, of which the folowing is a specification.

My invention .relates to an improvement in percolators, and the objects of myimprovement are, first, to provide simple and effective means to time and control the flow of an infusion from the peroolator; and, second, the provision of a practical device of the class of few parts easily cleansed and at comparatively low initial cost.

With the above and other objects in view, this invention consists in the novel features and in the combination' and arrangement of partshereinafter more specifically described, illustrated in the drawings, and particularly pointed out in the claims hereunto ap- In describing the invention in detail reference is had to the accompanying drawings forming a part of this specification whereln like numerals of reference indicate corresponding parts throughout the several views, and in which I Figure 1 is a vertical central section with the parts assembled. Fig. 2 is a side elevation of the filtering cup. Fig. 3 is a section on line 3 3 of Fig. 1. Fig. 4 is an inverted plan view. Fig. 5 is a detail view of the recesses and disk of the screw down valve.

One embodiment of my invention, in its more narrow aspects, will now be described.

The reference numeral 8 represents afluid receptacle, or coer-lpot, and the percolator proper com rises a ter holder 9 ,f and a filter `cup 10. T e upper portion12, of the cup 10, is imperforate and has no cover, but Is provided with ears 16, for the purposes of rotating the cup and for handling. The lower portion 11 o the cup is perforated, exce ting the portion of the bottom indicated y 11a in Fig. 3. On the bottom of the cup is a male threaded collar 13, with an annular flange 14, and an internal annular flange 15. Preferably the collar is made separately and soldered to the bottom, but it may be made integral therewith or in any suitable or desired manner. The filter holder 9 hasan external annular bead 29 to rest upon the top of receptacle 8, tapering lower portion 17,

l cup-shaped bottom 18, screw threaded ex,-

tension 20, annular flange 21, port` 22, and recesses 31. For 4the pur ose of more certainly securing a water ti t engagement of ,the members 13 and 20, w at I term a screw fdown valve, I provide a non-metallic apertured disk 23 of cork. If desired this isk may be omitted. The outwardly flaring bottom 24 has a series of perforations 25 to permit a wider distribution of the fluid that may readily pass through the clarifying or textile strainer 27, and to admit air to pass therethrough. On the outside of thev cupsha ed portion 18 is rovided lugs 26, opposite y positioned. T e clarifying strainer is hemmed at' the top and a split ring 28, inserted therein the usual manner, as shown in Fi 1. The handle 30, shown in Fig. 3, is usefu in putting` on and taking off the 4textile strainer. The ordinary cover 32 is provided for the holder 9.

It will be, obvious that the space between the holder 9, and the cup 10, and the recess 31, port 22, land perforation 25, will permit a free action. of gravity in the movement of the fiuid when collar 13 is unscrewed somewhat and thus its lower end raised from the disk 23.

To dispense with the use of eg or other clarifying means I employ a texti e strainerV to seat the threaded collar on the disk and poured into the cup and allowed to run fghrough making the desired quantity of cof` Manifestly changes in the form and arrangement of arts may be resorted to without departing from the s irit and scope of my invention. Therefore, do not wish to be limited to the exact construction shown and described in the preferred form of my `im provement.

v Having thusfully described my invention,

What I claim as new, and desire to secure by Letters-Patent, is

1. A percolator com rising a filter holder having a sereW threa ed extension on the bottom thereof With a ort therein, a perforated filter cup disposed) above the bottom of the holder and having a threaded collar on the bottom thereof, the bottom of the cup being imperforate Within the threaded portion, said collar being adapted to engage the eX- tension to control the outflow of uid from y the peroolator.

2. A percolator oom rising a filter holder having a screw threa ed extension with a port therein, an apertured disk normally7 seated on the bottom of the extension, a perforatediilter cup of less cross section than the holder and being imperforate Within the threaded portion and having a threaded eollar adapted to seat on the disk to prevent the out oW of fluid.

3. A percolator comprising a filter holder having a threaded extension of the bottom thereof With a recess and a port to permit the out flow of fluid, a non-metallic apertured disk, a filter cup With its upper portion i1nperforate and its lower portion erforated and carrying a threaded collar the ottom of the lter eup'being imperforate Within'the .thereof with an internal annular flange, the

bottom of the filter eup being iinperforate Within the threaded portion and a non-rnetallio apertured disk.

5. A peroolator comprising a filter holder having a threaded extension with a port and a plurality of recesses to permit out flow of fluid, a non-metallic apertured disk, a perf forated filter cup having a threaded collar on the bottoni thereof, the bottom of the filter cup being imperforate within the threaded portion, and adapted to engage said extension to control the out iiow of Huid from the pereolator.

In testimony whereof l allix my signature in-presence of two Witnesses.
